There are no stairs or corridors inside this house.
The site is flagpole-shaped, surrounded by neighboring houses with a building coverage ratio of 40%, and a family of five. The clear spatial composition of this house was rationally derived in order to obtain the maximum living space and good environment for severe conditions.
Only the rooms make up the interior. All non-residential elements such as corridors and stairs are placed outside and are not included in the volume and building area. As a result, while securing as many rooms as possible in a limited volume, a rich external space leads to an excellent environment.
It is necessary for the family to go outside once to go back and forth between each other's rooms. However, if you go outside and look from the stairs, you can see all the rooms and confirm the existence of the family.
While each individual is independent, they share a connection as a family. Such family relationships are contained in a space surrounded by concrete walls.
